自主測定挑戦

いくつかのフレーズは両方とも n という数字を参照し、 n

と呼んでいます。

• seven plus seven has 14 letters
• fifteen times one has 15 letters
• one followed by six has 16
letters
• one before two has 12 letters
• four before twenty has 16

この挑戦はもちろん無期限です。私は欲しい緑色の小切手を現在の最長の提出物に授与します（それが安価でないという条件で）。しかし長さに関わらず興味深い提出物をアップフォートしますので、長いものを発見できなければ落胆しないでください！

ガイドライン：

1. Syntactically, your phrase should be substitutable in
“__ is n”.

例えば、 all of my above examples fit this context:

four is 4
seven plus seven is 14
fifteen times one is 15
one followed by six is 16
one before two is 12
four before twenty is 16

2. Avoid extraneous and cheap additions.

The phrase eight and nine, maybe does
have 17 letters, but the maybe is rather
extraneous and cheap.

3. Avoid cheap recursion.

By appending and six to
four repeatedly, we can create a phrase
for any number of the form 6n+4. 例えば、

• four and six and six and six has 22
letters
4. Strive for human readability and
comprehension.

If an autonumerigram is very long but hard for a human to parse,
it loses points in my book. (Guidelines may be altered or
added as the need arises.)
