Since I couldn't find it in the docs (not that it isn't there;)
here are my hacks..

in gprolog-1.2.19/src/EnginePl

	./atom.c: (@line 59)

#define RADIX                      67
//Dhu #define INV_RADIX_MOD_MAX_ATOM     19563  /* see prog. euclide.c */
//#define INV_RADIX_MOD_MAX_ATOM     281707     /* see prog. euclide.c */
//Dhu ./euclide 67 2097152 ==> 281707.
// 1 << 21 = 2097152 ==> ATOM_SIZE in gprolog.h
//#define INV_RADIX_MOD_MAX_ATOM     61099115   /* see prog. euclide.c */
#define INV_RADIX_MOD_MAX_ATOM     10767467     /* see prog. euclide.c */

	./pl_params.h: (@line 33)

//Dhu ATOM_SIZE was 16  -- 65536, 21 gives 2097152, with hash of 281707
//Dhu ATOM_SIZE was 16  -- 65536, 24 gives 16777216, with hash of 10767467
#define ATOM_SIZE                  24
#define MAX_ATOM                   (1 << ATOM_SIZE) /* number of elements */

	./gprolog.h: (@line 226)

//Dhu ATOM_SIZE was 16  -- 65536, 21 gives 2097152, with hash of 281707
//Dhu ATOM_SIZE was 16  -- 65536, 24 gives 16777216, with hash of 10767467
#define ATOM_SIZE                  24
#define MAX_ATOM                   (1 << ATOM_SIZE) /* number of elements */
