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