Presentation

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

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

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