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