Folks, human vision is a better patter-detector than mathematics! Why not
just try varying the page-width of the digit stream until a pattern emerges?
Takes about 3 minutes!

You'll find there are missing / extra digits in the stream - and also a very
obvious explanation (well, obvious after the event!) for why overall number
of digits is no help... I don't want to give too much away - play with it
yourselves - but that margin-setting tip should get you started in almost no
time.

Enjoy.

All the best,

Richard
