Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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