Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

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