Does Fermat’s Last Theorem hold for cyclotomic integers in Q(ζ37)\mathbb{Q(\zeta_{37})}?

The first irregular prime is 37. Does FLT(37)


have any solutions in the ring of integers of Q(ζ37), where ζ37 is a primitive 37th root of unity?

Maybe it’s not true, but how could I go about finding a counter-example? (for any cyclotomic ring, not necessarily 37)
