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