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