Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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