Answers to Questions (FAQ)

What is an isogram?

Definition: An isogram is a word that contains repeated letters the same number of times, thus that presents letters the same number of times.

Example: WORD is an isogram (it contains one W, one O, one R and one D)

Example: DODO is an isogram (it contains two D and two O, all the letters are repeated once and therefore present twice)

Example: DCODE is not an isogram (it contains two D)

Example: ISOGRAM is an isogram (in self-reference)

What is the difference between an isogram and an heterogram?

A heterogram is a word that contains no repeated letter. All heterograms are isograms but only isograms with no repeated letters are heterograms.

What are the longest isogram words in English?

The english dictionary has isogramic words up to 16 letters: UNCOPYRIGHTABLES, HYDROPNEUMATICS (15), etc.

What is the Google Analytics Isogram?

Google uses a Javascript function for its Analytics application, which uses the letters I,S,O,G,R,A,M

Example: function(i,s,o,g,r,a,m)

In Javascript, the functions must have different arguments (which is the case for the letters of an isogram without repetition) and in order to save bandwidth, it is convenient to shorten the portions of code, so the use of single-letter arguments as in i,s,o,g,r,a,m is justified (a,b,c,d,e,f,g would have been valid as well).
