Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

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

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