Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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