English cardinal anagrams

From Rosetta Code
English cardinal anagrams is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Certain numbers, when spelled out in their English cardinal representation, are anagrams of other numbers.

Some are very obvious: sixty-seven <=> seventy-six

Others are a little more subtle: one hundred twelve <=> two hundred eleven


Task
  • Find and display the first thirty numbers that are a member of English cardinal anagrams, starting from zero.
  • Find and display the count of English cardinal anagrams from zero to one thousand.
  • Find and display the largest group(s) of English cardinal anagrams from zero to one thousand.


Stretch
  • Find and display the count of English cardinal anagrams from zero to ten thousand, restricted to numbers within those bounds. (Ignore anagrams of numbers outside those bounds. E.G. 1010 <=> 10001)
  • Find and display the largest group(s) of English cardinal anagrams from zero to ten thousand.

We get:

 67  69  76  79  96  97 102 103 104 105
106 107 108 109 112 122 123 124 125 126

If we consider all values in values in OEIS:A169936 which are less than 1e4

If we explicitly exclude anagrams whose only partner is greater than 1e4, we get a slightly smaller subsequence:

   #sam1e4
9228
   #~.ukgram sam1e4
2534

Note however that for values less than 1000, every member of the OEIS:A169936 sequence had a partner which was also less than 1000:

   #sam1e3
680
   +/1000>:sample
