Presentation

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

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

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