Presentation

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

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

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