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