Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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