Presentation

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

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

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