Presentation

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

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

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