Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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