Presentation

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

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

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