Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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