Presentation

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

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

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