Cuboctahedron
|
Med
Lrg
|
|
Description :
|
Make a cuboctahedron by aligning triangles with the 3-fold axes
of tetrahedral symmetry. Use twister notation.
View this model with the command
symmetro -t T[3,3],1,1 | antiview
|

|
Rhombicubo
|
Med
Lrg
|
|
Description :
|
Make a model like a rhombicuboctahedron by aligning triangles with the
3-fold axes and squares with the 4-fold axes of octahedral symmetry.
Scale the squares by 2. Use Kaplan-Hart notation.
View this model with the command
symmetro -k o,1,1,0 -r 2 | antiview

Snub cube
|
Med
Lrg
|
|
Description :
|
Make a snub cube by aligning triangles with the 3-fold axes and
pentagons with the 5-fold axes of icosahedral symmetry. Twist the
polygons by 28.53... degrees to produce a snub cube. Use twister notation.
View this model with the command
symmetro -t O[4,2],1,1 -a 28.53243959961367 -C f -D | antiview

Jitterbug
|
Med
Lrg
|
|
Description :
|
Make a twister, in this example Fuller's jitterbug, by twisting the
polygons with -a while suppressing the convex hull with -C s.
View this model with the command
symmetro -t T[3,3],1,1 -C s -a 15 | antiview

Sm st dod
|
Med
Lrg
|
|
Description :
|
Make an Sn-symmetry twister, in this example with 5/2 axes, and twist the
polygons by the axial angle of two edges.
View this model with the command
symmetro -s 5:2 -a 2e | antiview
|

J34
|
Med
Lrg
|
|
Description :
|
Make an C-symmetry twister, in this example with 5 axes and Ch symmetry,
producing a Johnson pentagonal orthobirotunda.
View this model with the command
symmetro -c 5,5,h | antiview

Near miss
|
Med
Lrg
|
|
Description :
|
Make an example near-miss symmetrohedron. Double the number of edges of the
polygon used for the 3-fold axis, and scale that polygons (which is on axis 1).
Set custom colours, which are mapped according to axis number.
View this model with the command
symmetro -t I[5,3],1,2 -m map_blue:purple:red:orange -r 1.07046626932,1 | antiview
