Presentation

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

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

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