a realy good idea,
and the transforms used on the superseeker lookup belong there too,
including their sometimes not-so-straightforward definitions:

List of transformations used:
T050  jth coefficient of Sn(z)*(1-z)^j

Abbreviations used in the above list of transformations:
u[j]	=	j-th term of the sequence
v[j]	=	u[j]/(j-1)!
Sn(z)	=	ordinary generating function
En(z)	=	exponential generating function
revogf	=	reversion of ordinary generating function
revegf	=	reversion of exponential generating function
lgdogf	=	logarithmic derivative of ordinary generating function
lgdegf	=	logarithmic derivative of exponential generating function

Subject: [seqfan] Transforms in the Wiki

One thing I would like to do when the Wiki is live is provide expanded coverage of transforms. It's not too early to start planning for this.

In particular,  I would like to see one page per transform.

So, do people think this is a good idea? If so, should we assign T-numbers? Any other suggestions? Can we just start creating such pages, or is some preparation required on the Wiki side?
