Presentation

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

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

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