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