Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(5,6,10,7)(8,9,12,11)(13,14,17,20,16,18,24,27)(15,21,23,26,22,28,25,19);(1,2,3,4)(5,7,9,12,10,6,11,8)(14,18)(15,22)(20,27)(23,25);(2,4)(13,15,16,22)(14,19,18,26)(17,25,24,23)(20,28,27,21);(5,8,9,7,10,12,11,6)
