Presentation

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

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

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