dear John, thanks for your hints.
|I point out that there is a nice method of John Dixon |for exact computation with cyclotomic integers by working |over a well chosen finite field F_p. |For algebraic integers there is the example of Darmon, Ford for |reconstructing exact values using p-adics. |This is in Comm in Algebra 17, (1989). |Lattice reduction may also be used. |John McKay . Does someone has a good pointer or link to start? . Does someone know about realisations/examples/lectures using GAP? I am very interested in reading more about what John sketched for exact computations using the above methods. Any hints are very welcome.
