Note: '''Niven''' numbers are also called '''Harshad''' numbers.
:::: They are also called '''multidigital''' numbers.
Line 14:
:* find the gap (difference) of a Niven number from the previous Niven number
:* if the gap is ''larger'' than the (highest) previous gap, then:
:::* show the index (occurrence) of the gap (the 1st gap is '''1''')
:::* show the index of the Niven number that starts the gap (1<sup>st</sup> Niven number is '''1''', 33<sup>rd</sup> Niven number is '''100''')
:::* show the Niven number that starts the gap
:::* show all numbers with comma separators where appropriate (optional)
:::* I.E.: the gap size of '''60''' starts at the 33,494<sup>th</sup> Niven number which is Niven number '''297,864'''
:* show all increasing gaps up to the ten millionth ('''10,000,000<sup>th</sup>''') Niven number
:* (optional) show all gaps up to whatever limit is feasible/practical/realistic/reasonable/sensible/viable on your computer
