Presentation

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

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

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