re(4): Solution ------ can you check? by K Sengupta)

If the rhs is positive, that is:

(a-5107)(b+5107) (mod L) = 26086391 = 4241*6151 = 6151*4241 = 1* 26086391 = 26086391*1

Then, (a, b) = (9348, 1044), (5108, 26081284)

For, (a, b) = (9348, 1044), we have:

1919*(9348)*(1044) (mod 5107)= 5106, so the first equation is not satisfied for these values. Indeed, the other four equations are not satisfied for these values.

Similarly, for (a, b) = (5108, 26081284), none of the five given equations are satisfied.

However, if the rhs is negative, that is (a-5107)(b+5107) (mod L) = -26086391, then:

(a, b) = (866, 1044), (5106, 26081284), as was demonstrated in *my original post*.

It may be verified that each of (866, 1044) and (5106, 26081284), satisfies the five given equations.
