Presentation

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

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

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