Find a 4x4 magic square with magic constant being 188 (base ten) and each of whose 16 entries is a non leading zeroes positive binary palindrome.

1, 3, 5, 7, 9, 15, 17, 21, 27, 31, 33, 45, 51, 63, 65, 73, 85, 93, 99, 107, 119, 127, 129, 153, 165,
The above is a list of the qualifying numbers for a,b,c,d as
copied from A006995 (oeis).
Clearly any four members of the above set, (y compris 27,27,27,107) qualify iff they add up to 188.
Nothing wrong with providing a list of all quadruples, however, if I read correctly the puzzle, the solver was asked to "Find a 4x4 magic square etc.." which I did.
btw, the bla-bla about leading zeroes was totally redundant.
