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