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