User:Tomruen/Uniform polyteron verf

Vertex figures (as Schlegel diagrams) for uniform polyterons, uniform honeycombs (Euclidean and hyperbolic). (Excluding prismatic forms, and nonwythoffian forms)

Tables are expanded for finite and infinite forms (spherical/Euclidean/hyperbolic) for completeness, not that I expect ever to include all of the hyperbolic forms! (Compare to 4-polytopes: Talk:Vertex figure/polychoron)

Spherical

edit

There are three fundamental affine Coxeter groups that generate regular and uniform tessellations on the 3-sphere:

# Coxeter group Coxeter graph
1 A5 [34]
2 B5 [4,33]
3 D5 [32,1,1]

In addition there are prismatic groups:

Uniform prismatic forms:

# Coxeter groups Coxeter graph
1 A4 × A1 [3,3,3] × [ ]
2 B4 × A1 [4,3,3] × [ ]
3 F4 × A1 [3,4,3] × [ ]
4 H4 × A1 [5,3,3] × [ ]
5 D4 × A1 [31,1,1] × [ ]

Uniform duoprism prismatic forms:

Coxeter groups Coxeter graph
I2(p) × I2(q) × A1 [p] × [q] × [ ]

Uniform duoprismatic forms:

# Coxeter groups Coxeter graph
1 A3 × I2(p) [3,3] × [p]
2 B3 × I2(p) [4,3] × [p]
3. H3 × I2(p) [5,3] × [p]

Euclidean

edit

There are five fundamental affine Coxeter groups that generate regular and uniform tessellations in 4-space:

# Coxeter group Coxeter-Dynkin diagram
1 A~4 [(3,3,3,3,3)]
2 B~4 [4,3,3,4]
3 C~4 [4,3,31,1]
4 D~4 [31,1,1,1]
5 F~4 [3,4,3,3]

In addition there are prismatic groups:

Duoprismatic forms

  • B~2xB~2: [4,4]x[4,4] = [4,3,3,4] = (Same as tesseractic honeycomb family)
  • B~2xH~2: [4,4]x[6,3]
  • H~2xH~2: [6,3]x[6,3]
  • A~2xB~2: [3[3]]]x[4,4] (Same forms as [6,3]x[4,4])
  • A~2xH~2: [3[3]]]x[6,3] (Same forms as [6,3]x[6,3])
  • A~2xA~2: [3[3]]]x[3[3]] (Same forms as [6,3]x[6,3])

Prismatic forms

  • B~3xI~1: [4,3,4]x[∞]
  • D~3xI~1: [4,31,1]x[∞]
  • A~3xI~1: [3[4]]x[∞]

Hyperbolic

1 [5,3,3,3]
2 [5,3,3,4]
3 [5,3,3,5]
4 [5,3,31,1]
5 [(4,3,3,3,3)]

Linear Coxeter graphs

edit

There are 31 truncation forms for each group, or 19 subgrouped as half-families as given below (with 7 overlapped).
