[seqfan] Re: How to list pairs, triples, etc.

[N. J. A. Sloane]

Richard,  You asked how to enter a list of triples.

The answer is to create four sequences,
one which reads the tribles across the rows of a table with 3 columns,
so
a b c
d e f
g h i
j k l
...

becomes the sequence  a b c d e f g h i ...
with keyword "tabl" (for nontriangular table)

and then also to submit the three columns as 
separtae linked sequences:

a d g j ...

b e h k ...

and

c f i j ...


 Best regards
