Presentation

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

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

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