Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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