Presentation

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

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

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