Presentation

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

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

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