Acronym rojkohgyt
Name rojak honeycomb gyrotrigonism
Lace city
in approx. ASCII-art
     		where:
    B		A = o3x3o3o3o *c3o3o (rojkoh)
A    		B = o3o3o3x3o *c3o3o (gyro rojkoh)
    C		C = o3o3o3o3o *c3x3o (alt. gyro rojkoh)

This euclidean honeycomb uses rojkoh and rojkoha in the sense of infinite horohedra. Note however, as a gyrotrigonism, within position space of the lace city display, it just happens to remain of finite reach. Thence it more looks like an infintely long triangular needle.
