Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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