yes, isocelen or isocelon or isocelesic, with the unit isoceles being the regular tetrahedron; now, it is proven that the tetrahedron is skew tetragon in three ways.... incidentally, the first three fibonacci#s give either a) 1x2x1 rectangular box, or, if they are the lengths of the pairs of edges of the isocelon, the box around it is the secondr00ts of (5,1,5). however, I guess that the canonical mode would just be to use the three pairs of lenghts to be secondr00ts, which gives secondr00ts for the cicumscribing box, as well
