 
LEO is a FORM code for the calculation of the three-loop single scale bubble type diagrams. The full set of solved recurrence relations is presented in hep-ph/9512442 . The one of application - the calculation of the QCD corrections to the electrowek rho-parameter within SM - is done in hep-ph/9406363 .
 The construction of the epsilon-expansion 
for diagrams relating to QED/QCD problems
(in particular, BN(0,0,1,1,1,1))
was investigated by David Broadhurst
in Z.Phys.C54 (1992) 599-606 
and 
  hep-th/9604128 .
