Under-tested cosmetic edits made to the task page at 21:04, 15 May 2016, including the injection of spaces around expressions in <math> tags, have left some or all of the task description formulae completely invisible to all browsers which display the graphic file version of formulae rather than processing the MathML (this is, in fact, the majority of browsers). The MediaWiki processor does not currently expect such spaces, and generates syntactically ill-formed HTML if they are introduced. Other aspects of these cosmetic edits may further compound the problem. [[User:Hout|Hout]] ([[User talk:Hout|talk]]) 18:59, 22 September 2016 (UTC) |

task?
I see that although shuffle is not specified we have two implementations. But I have no way of knowing if they are correct implementations. Perhaps we should have an example? With this starting seed, we have this deck of cards? --Rdm 11:15, 19 September 2011 (UTC)
Example
I know this doesn't give the shuffle algorithm but ... it gives the result for seed=1 [1] and appears compatible with [2]

There is a reference to the shuffle algorithm here [3]

32 bit Perl fix
The sample code for Perl works for perl 5.16 64 bit but not for perl 5.8 32 bit (e.g. game# 1070). This fix works for both.
# return (($s = ($s * 214013 + 2531011) & 0x7fffffff) >> 16 );
return (($s = ($s * 214013 + 2531011) % 2**31 ) >> 16 ); # fix for 32 bit perl
equation clarification
The equation:
should probably read
![{\displaystyle state_{n + 1} \equiv [ 214013 \times state_n + 2531011 ] \pmod{2^{31}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/bb12534e1143260cb4383279c1474faacd1295e0)
