Presentation

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

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

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