Presentation

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

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

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