How do I do this? The array is only a 4X4 array, but the elements are long algebraic expressions which are not fitting onto a page even if I use tiny fontsize and landscape orientation. I have experimented with align and split and haven't had much success. I get errors like:<br><br>! Package amsmath Error: Erroneous nesting of equation structures;<br>(amsmath) trying to recover with
`aligned'.<br><br>Thanks,<br>Sally<br></div></div></div></div></body></html>
