Presentation

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

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

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