[Response to previous message on Sun-4 "bug" by Sean Doyle. -smc]

Here is a session on my Sun-4/110 running 1.2 beta:

Mathematica (sun4) 1.2.beta (April 2, 1989) [With pre-loaded data]
by S. Wolfram, D. Grayson, R. Maeder, H. Cejtin,
   S. Omohundro, D. Ballman and J. Keiper
with I. Rivin and D. Withoff

In[1]:= <<lagbug.m

In[2]:= Delta[1] Delta[100] Delta[3]

Out[2]= ApplyLag[Identity  - LagOperator[1] - LagOperator[3] + 
>     LagOperator[4] - Identity  LagOperator[100] + LagOperator[101] + 
>     LagOperator[103] - LagOperator[104]]


Which appears to agree with your 1.1 3/60 answer.  So, something
seems better.  I will be getting the official non-beta 1.2
today.  I will ship you message and this one to the mailing list
