### matho-primes: generate consecutive prime numbers

## NAME

matho-primes - generate consecutive prime numbers

## SYNOPSIS

**matho-primes**[start [stop]] ["twin"] ["pal" [base]]

**matho-primes**[-t] [-p base] [start [stop]]

## DESCRIPTION

This command line utility is optionally part of the**mathomatic**(1) package. It quickly computes any number of consecutive prime numbers using a windowing, memory efficient sieve of Eratosthenes algorithm, dumping them to standard output. They are displayed one prime per line in ascending order, unless the "twin" option is specified, which displays only twin primes, two primes per line.

Generates up to 18 decimal digit primes,
or whatever is the number of digits of precision for a
**long double**
in the C compiler used to compile this utility.

A range may be
specified on the command line, otherwise the starting number and
the number of primes to output is prompted for.
The range is
**start**
to
**stop**
inclusive, and
**stop**
must
be greater than or equal to
**start.**

If the "-t" or "twin" option is specified on the command line,
only
**twin primes**
will be displayed.
Twin primes are two primes that differ in value by 2.
Each twin pair is displayed together on the same line separated by a space character.

If the "-p" or "pal" option is specified on the command line,
only
**palindromic primes**
are displayed.
Palindromes are symmetrical, they read exactly the same forward and backward.
The palindrome number
**base**
may be specified, the default is base 10.
The
**base**
can be any integer greater than 1.
