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