Acronym gabirch Name great birhombatocubic honeycomb Confer variants: case 0 < b:a < 1/sqrt(2) / case b:a = 1/sqrt(2) / case 1/sqrt(2) < b:a < 3/sqrt(2) / case b:a = 3/sqrt(2) / this case 3/sqrt(2) < b:a < ∞ general polytopal classes: isogonal

This honeycomb is the general form of one of the 3 phases of the tegum sum of 2 inverted general srich variants, ao4ob3bo4oa&#zc, here in fact the realm of 3/sqrt(2) < b:a < ∞. The other ones will be sabirch for 0 < b:a < 1/sqrt(2) resp. mabirch for 1/sqrt(2) < b:a < 3/sqrt(2).

Further there are singular transition cases too. The relevant ones for the current realm are the bordering cases b:a = 3/sqrt(2) (rebatch) and b:a → ∞ (bamich) respectively.
