Presentation

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

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

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