Command for Equation Plot [Implicit] hard to fathom. Need help please.

Software G'MIC
1

As per the title, I have tried a number of different ways to format the equation part of the command for this filter, with no luck.
Here’s some of what I have tried so far:

gmic 600,600,1,3 cl_implicitEqua ( x^2 + y^2 - 25 )   *   ( (x-2)^2 + (y-2)^2 - 1 )   *   ( (x+2)^2 + (y-2)^2 - 1 )   *   ( abs(x) + abs(y) - 1 )   *   ( x^2 + (4*y+12-x^2)^2 - 9 ),600,600,-6,-6,-6,-6,0,0,2 o output.png

(This last error msg is very weird, as it seems to reference some files in my current working directory!)

Maybe I’m doing something else wrong… not sure.

With gmic version 3.7.2 on Android (Ubuntu/proot-distro) terminal emulator.

Cheers.

G’MIC is space-sensitive, so remove spaces. And two, show the code.

Ok. So I got rid of the spaces and did:
gmic 600,600,1,3 cl_implicitEqua \"\(x^2+y^2-25\)*\(\(x-2\)^2+\(y-2\)^2- 1\)*\(\(x+2\)^2+\(y-2\)^2-1\)*\(abs\(x\)+abs\(y\)-1\)*\(x^2+\(4*y+12-x^2\)^2-9\)\",600,600,-6,-6,-6,-6,0,0,2 c 0,255 o output.png

EDIT: My bad, I copied part of the default command wrong, so now it’s working… just need to figure out how to make the strokes thicker.
Thanks for your help!
