Pangram
Encyclopedia
A pangram or holoalphabetic sentence, is a sentence using every letter of the alphabet
Alphabet
An alphabet is a standard set of letters—basic written symbols or graphemes—each of which represents a phoneme in a spoken language, either as it exists now or as it was in the past. There are other systems, such as logographies, in which each character represents a word, morpheme, or semantic...

) to display computer fonts. The German Victor-jagt pangram, used since before 1800, contains all the letters, including the 3 umlaut letters: ä, ö, ü.

Short pangrams tend to be more interesting and more difficult to write because the English language uses some of the same letters (especially vowels) much more frequently than others. Longer pangrams may afford more opportunity for humor, cleverness, or thoughtfulness. In a sense, the pangram is the opposite of the lipogram

Logogram

Self-enumerating pangrams

A self-enumerating pangram, or a pangrammic autogram
Autogram
An autogram is a self-referencing sentence that describes its content.An example autogram would be: This sentence contains only three a's, three c's, two d's, twenty-five e's, nine f's, four g's, eight h's, twelve i's, three l's, fifteen n's, nine o's, eight r's, twenty-four s's, eighteen t's, five...

Lee Cecil Fletcher Sallows is a British electronics engineer known for his contributions to recreational mathematics. He is particularly noted as the inventor of golygons, self-enumerating sentences, and geomagic squares...

 (a British electronics engineer). Hofstadter posed the problem of sentences that describe themselves, prompting Sallows to devise the following:

Only the fool would take trouble to verify that his sentence was composed of ten a's, three b's, four c's, four d's, forty-six e's, sixteen f's, four g's, thirteen h's, fifteen i's, two k's, nine l's, four m's, twenty-five n's, twenty-four o's, five p's, sixteen r's, forty-one s's, thirty-seven t's, ten u's, eight v's, eight w's, four x's, eleven y's, twenty-seven commas, twenty-three apostrophes, seven hyphens and, last but not least, a single !


This is not a complete pangram as it lacks a j, q, and z. Kousbroek published a Dutch equivalent, which spurred Sallows, who lives in the Netherlands and reads the paper where Kousbroek writes his essays, to think harder about this problem in order to solve it more generally. Initial attempts to write a program for this came to naught, but, in 1984, he decided to construct a dedicated piece of hardware for this task. The Pangram Machine, as Sallows called his device, accepted a description of the initial sentence fragment and tried to fill in the blanks. The result was later published in Scientific American in October 1984:

This Pangram contains four as, one b, two cs, one d, thirty es, six fs, five gs, seven hs, eleven is, one j, one k, two ls, two ms, eighteen ns, fifteen os, two ps, one q, five rs, twenty-seven ss, eighteen ts, two us, seven vs, eight ws, two xs, three ys, & one z.
