Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
gap> G := Group((2,7,25,15,19,33,29,51,20,22,52,43,45,3,11,35,24,14,12,46,47,9,40,49,27,16,5,18,10,6,31,28,44,38,21,32,53,26,36,8,4,17,13,34,30,50,48,23,39,41,42,37), (1,2,6,16,29,43,25,13,32,42,4,12,28,47,46,53,45,31,18,38,14,35,23,8,20,40,41,49,39,21,3,9,17,34,51,7,19,36,52,50,48,33,30,11,27,22,24,10,26,44,37,15,5)(54,55));
