Presentation

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

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

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