Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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