Presentation

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

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

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