The editor accepts up to 128 nodes and 512 edges and trifundamentals together. Drawing or importing a large quiver does not bypass the calculation's time, work, memory or mathematical checks. Use Coulomb to run that branch alone; Cancel retains completed coefficients.
Circles are gauge groups; squares are flavour groups. Select a node to choose U(n), SU(n), SO(N), O(N), USp(n), G₂, F₄, E₆, E₇, E₈, or a finite Zq gauge factor. For USp, enter the even defining dimension n; for SO/O, enter vector dimension N. USp(n) shows n inside the node. Existing JSON continues to store its Cartan rank n/2. Exceptional nodes display their group name and have fixed Cartan rank; ordinary edges use their minimal representations of dimensions 7, 26, 27, 56 and 248 respectively. SU(n) has Cartan rank n−1; Zq has Cartan rank zero. SO gauge nodes offer SO, Spin or the even-dimensional PSO global form, and O gauge nodes offer O+, O− or Pin+. Odd-dimensional O nodes also expose the source-prescribed charge-conjugation parameter δ. O+ remains the default. Plain edges are full hypers; dashed edges are half hypers. Auto chooses half hypers for SO/O–USp and full hypers otherwise. Multiplicity counts repeated hypers or copies of a bond. Add adjoint, symmetric or antisymmetric full-hyper loops by connecting a gauge node to itself, or through its inspector. The default symmetric/antisymmetric tensor includes any invariant singlet; the Traceless option removes it for SO/O symmetric and USp antisymmetric tensors. Explicit half hypers also support SO/O–SU(2), G₂/F₄/E₈–USp and SO/G₂/F₄/E₈–E₇; the engine checks gauge consistency. Other pairs and spinor matter are unsupported. Neutral ordinary hypermultiplets are retained separately on the canvas and in JSON. Their Coulomb factor is 1; finite unrefined Higgs calculations multiply by (1−t)^(−2h). Their refinement, Higgs rational modes and Higgs-union composition are explicitly unavailable. U flavour nodes may have dimension up to 1000; gauge limits remain unchanged. A determinant full-hyper loop on U(n) has weight sum_i m_i and central charge n; its unrefined Coulomb calculation is supported, while Higgs, refinement and decay reject it explicitly. Coupled determinant-one U-node pairs are preserved as trace constraints, drawn as dashed annotated links. Their unrefined finite Coulomb sum imposes each paired trace equation and removes one central Casimir per equation. Compatible constrained pairs are joined before tree gluing to reduce intermediate storage; unavailable operations reject explicitly. Charged matter is edited within the Bifundamental inspector. The endpoint coefficients specify qₛwₛ − qₜwₜ; negative unit coefficients select conjugate U/SU representations. Nonunit charges apply to U(1), SO(2) and Zq endpoints. For SO(2), choose explicitly between its two-weight vector and a one-weight character. Exceptional higher representations are additional hypers selected by Dynkin label in the node inspector; their calculation support is reported by the engine.
Non-simply-laced bonds support U/SU–U/SU and SO–USp in either direction, with integer lacing ℓ from 2 to 30. They are distinct from repeated bifundamental hypers. The arrow points from the scaled long source to the short target. A U–U bond contributes Σᵢⱼ|ℓ m_source,i − m_target,j| to 2Δ per copy. An SO–USp bond uses Fig. 1 of Folding Orthosymplectic Quivers (arXiv:2107.00754): Σᵢⱼ(|ℓ m_source,i − m_target,j| + |ℓ m_source,i + m_target,j|). If SO is odd-dimensional, add Σᵢ|ℓ m_source,i| when USp is the source, or Σⱼ|m_target,j| when USp is the target. Multiply the entire contribution by the copy count. A flavour endpoint has zero magnetic charge. The paper’s orthogonal nodes are SO groups; O+–USp non-simply-laced bonds are not supported. Reverse direction in the edge inspector. These bonds do not specify a full or half hypermultiplet representation: Higgs computation is unavailable even with flatness checking off. Hasse computation supports unitary quivers with full adjoint loops, ordinary and non-simply-laced bonds; other tensor loops and orthosymplectic bonds remain outside its domain.
Choose Trifundamental and click three distinct nodes to add one three-legged tensor-product hypermultiplet. All-flavour trifundamentals are free matter with a point Coulomb branch. The default is a full hyper with all U legs fundamental. Select the diamond junction to edit copies, full/half matter, and each U leg’s fundamental or antifundamental sign. SO/O/USp legs are self-dual. Half trifundamentals use real SO/O and pseudoreal USp or SU(2) legs, with an odd number of pseudoreal legs; additional consistency checks apply in the engines. Deleting a node removes its attached trifundamentals. Ordinary common-shift diagonal U(1) removal is disabled when a trifundamental is present. Use Quotient continuous centre kernel to remove every trivially acting U(1) direction determined by the complete matter-charge matrix; this preserves the selected lattice convention reported by the engine.
The main Higgs and Coulomb tabs are unrefined. The Refined Hilbert series tab retains flavour weights for supported unitary quivers, with selectable order, an irreducible-representation view and a refined plethystic logarithm. Hypermultiplet coordinates have degree t; vector-multiplet complex scalars have degree t²; a monopole of conformal dimension Δ contributes t²Δ. “Through tⁿ” means coefficients through degree n inclusive, with remainder O(tⁿ⁺¹). These are truncated graded expansions, not a coupling expansion.
