Although all cells individually have uniform realisations, the honeycomb as a total can not be made uniform: The mere alternated faceting (here starting at otch) e.g. would use edges of 3 different sizes: |sefa(s4s)| = x(8) = sqrt[2+sqrt(2)] = 1.847759, |s2s| = x(4) = sqrt(2) = 1.414214, and |sefa(s3s)| = x(6) = sqrt(3) = 1.732051 (refering to elements of s4s3s4s here).
