Presentation

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

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

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