Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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