A super-d number is a positive, decimal (base ten) integer &nbsp; '''n''' &nbsp; such that &nbsp; '''d × n<sup>d</sup>''' &nbsp; has at least &nbsp; '''d''' &nbsp; consecutive digits &nbsp; '''d''' &nbsp; where
where
<big>2 ≤ d ≤ 9</big>
<big>2 ≤ d ≤ 9</big>
For instance, 753 is a super-3 number because 3 × 753³ = 128087<u>333</u>1.
